It is said that the architect Achille Larducci, in building the sumptuous building with curvilinear shapes in 1667, wanted to pay homage to the Borrominian church of San Carlo alle Quattro Fontane in Rome.
Built on a previous fifteenth-century building, belonging to a convent of Franciscan Tertiaries, the church has a facade with two orders, divided by a protruding curvilinear frame, while the interior has a large elliptical nave, marked by pilasters on which are placed the statues of the Apostles. The nuns attended the liturgical functions from the mullioned windows of the nave.
